This project is a manual alignment and stamping jig designed for 3 mm metal letter stamps, allowing clean, straight, and evenly spaced lettering on metal plates.
The jig is fully 3D printed in PLA and works as a guided manual press, ensuring that each letter stamp remains:
- vertically aligned,
- evenly positioned,
- and perpendicular to the work surface.
The system is especially useful for steel (stainless) nameplates, tags, labels, or samples, where free-hand stamping often leads to misalignment or uneven depth.
The stamped steel plate shown in the photos (“MASTER”) is an example of the achievable result.
Key Features
- Designed specifically for 3 mm metal letter stamps
- Linear sliding carriage with rack-guided alignment
- Square anti-rotation holder for accurate stamp orientation
- Manual downward force only (hammer or hand press on wood or leather)
- Optimized for repetitive, clean lettering
No electronics, no calibration, no consumables
How to Use (Important)
- Place the jig on a very solid, non-flexing surface
→ A heavy steel mass, an anvil, or a thick steel block is mandatory.
❌ Do not use on a desk, wooden table, or any flexible surface. - Position the metal plate on the steel backing surface inside the jig.
- Insert a 3 mm metal letter stamp into the square holder, ensuring it is fully seated and vertical.
- Slide the carriage to the desired position and hold it firmly.
- Using a heavy hammer, apply one single, straight, controlled удар (strike) on the stamp.
→ Do not tap multiple times.
→ Do not use light or angled hits. - Move the carriage to the next position and repeat for each letter.
